Dry-break coupling under pressure

Dry-break coupling under pressure

Tropffreies Kuppeln unter Druck Serie DBG-CUP

The special feature of the DBG-CUP is its possibility to connect a pipe with a hose without pressure relief, whereas both of them can be under pressure. The series owes this property to the unique CUP SYSTEM. The CUP valve is designed in such a way that the system pressure has hardly any influence on the coupling force.

  • Special series DBG-CUP, DN 12 to 25

  • Dry-break, robust and safe for every application

  • CUP SYSTEM – connection under pressure

  • Unique in its class
